The Decimator guitar pedal offers a new approach to noise reduction processing. Most noise suppression systems suffer from one major problem inherent in their design: The system cannot be immediately responsive to very short-term staccato notes. The typical downward expander sound reduction system suffers from a dead zone in the release response characteristic that causes a compromise in tracking both fast decaying notes and long sustained notes. The Decimator pedal's design offers a novel approach to tracking the envelope of the input signal called Time Vector Processing.

Due to this novel approach in controlling the expander, the Decimator system will instantly respond to short staccato notes and, at the same time, will provide a very slow ripple free control of long sustained notes. The Decimator noise suppression system is very transparent delivering high performance.

The Decimator pedal by ISP Technologies is extremely easy to use; simply insert the Decimator at the end of your chain of existing pedals or, insert the Decimator Pedal in the effects loop of your amplifier to clean up the noise present at the amplifier input as well as the noise in the amplifiers pre-amp section. Packaged in a rugged, beautifully polished smooth chrome chassis, the Decimator pedal offers reliability, performance and beauty in one compact pedal.

This thing is simple and effective, period. It has an on/off pedal (exactly like a standard Boss pedal) and one dial that you simply dial in based on the conditions you are playing in and the gear you're using. I literally had it up and running almost instantly. I took the Decimator out of the box, velcroed it to my pedal board, plugged it in, hooked up a guitar, and turned the dial until the feedback and crappy noise went away. I did not notice any appreciable drop off in tone whatsoever, and I am pretty attentive to tone. As soon as I stopped playing, there was ZERO noise, it really is amazing. My signal path: Les Paul with 496/500T ceramic humbuckers through a Sennheiser Wireless, Sonic Research Turbo Tuner, Dimebag Crybaby Way, Jekyll and Hyde Distrortion/Overdrive, Boss flanger, MXR delay and Decimator (all powered by a Voodoo Pedal Power) into a Tech 21 Trademark 60 amp. I put my decimator at the end of my signal chain, even after the modulation effects, and it seems to work perfectly. My rig was not particularly noisy to begin with (use good cables!) but I'm glad I got this. You should not hesitate to buy it, can't imagine anyone being disappointed with it.

After reading tons of rave reviews and comparing this with other noise reducing pedals I went ahead and ordered it. This pedal was a disappointment...it does not track the notes as close as they say (it will choke long notes out, even at minimal settings), and it lets the noise through when you play. It works like a gate...a decent gate, but a gate. It does not alter your tone when you're playing because the gate is fully open, and it closes fairly smoothly. As soon as you stop playing it's silent, but once you start again you've got all the hiss and hum as usual. This works best when playing at very high gain, when the hum and noise are buried in the distortion. It does kill feedback; you can crank a high gain amp and stand right in front of it with complete silence and no feedback (if you wanted to). Probably good for hard rock, punk, metal, and shredding, but not for clean playing, or for cleaning up single coils. I really wanted to like it, but I'll be returning it soon.

I would say its only effective on high gain settings. It's a gate and that's it. Decaying notes don't fade smooth and noise trails with it. The sustain is cut off early. Of course if you are using high gain or heavy distortion setting you don't notice this as much. Any decent gate can do what this does, and more, for way less money. I don't hear any noise filtering at all. Just open or closed. It's basically a hard gate, and that's it. Noise, or no noise and that's it, with no finesse in between. Why not at least put a decay nob so you can adjust how fast or slow the gate closes, because it does not track the natural decay of a clean sound well at all. I'm sure that's why the G model followed shortly after to compensate for this, which is really a Boss concept to begin with. The MXR and Boss noise gates are so much more flexible.

This pedal is hands down the best noise suppressor pedal. it cleans up your tone without adding to it. it looks absolutly beutiful. the only problems are that it gets finger-prints all over it and it adds a considerable amount of weight, 2.2 Lbs., to your board.overall this is one of the best purchases I've bought online. Well done ISP!

This pedal works as advertised, kills hum and excess noise when you are not playing. Works well to kill noise and excess feedback in an enclosed space when in overdrive on a tube amp. It does let feedback through still, depending on how high you turn the knob, which is a good thing.I only needed to turn the knob up about 25% to take effect. Doesn't seem to bother a clean signal unless you turn it up too much. Eats a battery in a few hours, so I'm going to buy an ac adapter.

This is an update for a former review. These units eat up batteries quickly - averaged about 4 hours continual use per battery - OK for a gig. But, for practice and forgetting to unplug the input, recommend the Morley 9-volt power adapter which MF sells. Works great. Funny, ISP offers no info in recommending any kind of 9-volt adapter - BOO - HOO on them.

I put mine in my jvm loop with an ns2 in front. Best setup for noiseless operation. Be warned you NEED to use a power supply with this unit it is not intended to run on a batteryOne knob, very simple. Easiest operation you could ask for!Solid metal and super durable. Worth almost every penny!

When I use just an overdrive pedal this noise gate gets turned off. It isn't needed and will cut off your signal.

The instruction booklet inside shows a recommended way to use this pedal...It is advised to be used at the very end of a pedal train. I use my and plug it directly into the front of the amp. You can use it in the effects loop but it's pointless if your not running gain pedals through the loop.

Anything ran after this pedal on a signal path will be cut off so this is why this pedal is placed at the end of a pedal board and then into the amp.

Digital interface ie: POD's allow you to run a simulated noise gate in the middle but that's all simualted computer generated effects.A real analog noise gate like this one is ran at the end of the path...

This pedal is a little pricey but worth it's weight once you get it and see how well they actually work. I would recommend this pedal to anyone whom loves to run a hot signal through their amp and has lots of fee-back from gain.

Yea, it works - fantastic gate! Great pedal. I've used it for recording and now my son's heavy metal band "Remnants of Camulos"use two of them - one for each guitarist. They play LOUD. When practicing in the small basement room, the pedal is a godsend as it cuts out the aweful feedback when they pause. It is very well built.They must sell thousands of these pedals - so I think the price should be less.
